How can I print the contents of a hash in Perl?
...
Data::Dumper is your friend.
use Data::Dumper;
my %hash = ('abc' => 123, 'def' => [4,5,6]);
print Dumper(\%hash);
will output
$VAR1 = {
'def' => [
4,
5,
6
],
'abc' => 123

Hg: How to do a rebase like git's rebase
...e:
1. Start working on a new feature:
$ hg clone mainline-repo newfeature-123
do a few commits (M, N, O)
master A---B---C
\
newfeature-123 M---N---O
2. Pull new changes from upstream mainline:
$ hg pull
master A---B---C---D---E---F
\
newfeature-123 M---N---O

Parse query string into an array
...alone is note accurate, it could display for example:
$url = "somepage?id=123&lang=gr&size=300";
parse_str() would return:
Array (
[somepage?id] => 123
[lang] => gr
[size] => 300
)
It would be better to combine parse_str() with parse_url() like so:
$url = "som...
How to calculate “time ago” in Java?

Why would I ever use push_back instead of emplace_back?
... will be invalid after the call.
std::vector<int> v;
v.emplace_back(123);
v.emplace_back(v[0]); // Produces incorrect results in some compilers
On one compiler, v contains the values 123 and 21 instead of the expected 123 and 123. This is due to the fact that the 2nd call to emplace_back re...
